Connectivity sensible, the chip still utilizes a LTE category 4 modem with as much as 150Mbps down and 50Mbps up speeds, however the brand-new RF system consists of optimisations for power use, such as the new addition of eDRX (Extended alternate reception) for far better power efficiency. Bluetooth connection has been updated to the 5.0 standard.
An interesting addition to the SoC is a second ISP. The new chip has the ability to now handle double 16MP cameras– some of Qualcomm’s clients have concepts for smartwatch items which would deploy 2 electronic cameras.
Qualcomm continues to utilize a primary SoC+co-processor architecture for its smartwatch platforms. The abovementioned Wear 4100 works as the main processor chip throughout active and interactive usage of the gadget, whilst a secondary co-processor works as the always-on silicon that has the ability to allow ambient non-interactive device use-cases (Essentially, powering on the screen with fixed/ low-updating information).
The brand-new SoC is a complete overhaul in regards to design. As discussed, instead of the quad-core A7 cores at 1.1 GHz, the new chip now includes quad A53 cores at up to 1.7 GHz. The chip still relies on LPDDR3 as its memory technology however the clock rates have been upped from 400MHz to 750Mhz. The GPU has actually seen a huge leap in performance as it sees the jump of 2 architectural generations from an Adreno 304 to a brand-new Adreno 504. The chipset likewise seen its DSP capabilities expanded as it now features a second dedicated audio DSP for actual application side processing (Alongside the modem DSP) that previously didn’t exist on the Wear 3100 chip.
The overall enhancements of the platforms bring a -20% decline in power usage, all whilst increasing CPU efficiency by 85%, GPU efficiency by an enormous factor of 2.5 x. In regards to work effectiveness, you’ll be seeing considerable boosts– all needed in wearable devices as battery life is key.
The co-processor can act as the sensor center collecting information from your common smartwatch sensors, all whilst the primary SoC is powered off.
The primary SoC is now made on a more recent 12nm procedure node at TSMC– it’s certainly not the newest node provided a brand-new platform like this, however Qualcomm probably made their cost-performance estimations when picking this design aspect.
The co-processor has a comparable style to the QCC1110 that was bundled with the Wear 3100 platform, but has actually been improved in terms of a few of its abilities such as having richer colour depth rendering capability for approximately 16 bit (64K colours).
The crucial element for using both a primary SoC and a co-processor in the very same gadget is the dual screen architecture of the system, where the display screen is linked to both chip and can receive signals from both. The reason for Qualcomm to not have actually carried out a single monolithic chip is rationalised by design efforts and cost-opportunity; while they have not announced any items yet, they envision the possibility to utilize the QCC1110 as a standalone system in a device, and likewise, one can utilize the Wear 4100 without a co-processor.
Today Qualcomm is making a huge action forward in its smartwatch SoC offerings by presenting the new Snapdragon Wear 4100 and Wear 4100+ platforms. The new chips prosper the aging 2 2018 stemming Wear 3100 platforms and significantly upgrading the hardware requirements, giving the table all new IPs for CPU, GPU and DSPs, all made on a newer lower power process node.
Smartwatch items over the last couple of years had always one big criticism to them, which was the fact that the SoCs powering them were constantly seemingly underpowered compared to what we’re seeing from the like of vertically incorporated vendors such as Apple and their own smartwatch SoCs. Qualcomm’s new Wear 4100 SoC now lastly deserts the Cortex-A7 cores and 28nm procedure in favour of Cortex-A53 cores and a 12nm process– whilst certainly not bleeding edge, it’s a big jump in performance and power performance.
The Snapdragon Wear 4100 platform represents the main SoC and surrounding vital components, whilst the Wear 4100+ platform likewise consists of the co-processor for augmented always-on operation. The new platforms are available and shipping to suppliers now.
The new SoC is a total overhaul in terms of design. Connectivity smart, the chip still uses a LTE category 4 modem with up to 150Mbps down and 50Mbps up speeds, but the new RF system consists of optimisations for power use, such as the brand-new addition of eDRX (Extended discontinuous reception) for much better power performance. Qualcomm continues to use a main SoC+co-processor architecture for its smartwatch platforms. The key aspect for utilizing both a main SoC and a co-processor in the same device is the double display architecture of the system, where the display is connected to both chip and can get signals from both.
